St. John Vintage Evening Collared Zipper Jacket Rhinestones Size 12

Vintage, knit evening jacket, embroidered collar, back-cut-outs, zipper, beautiful rhinestone detail. Sewn in shoulder pads. It is in excellent condition. One small hole has been repairs on the back of one shoulder (photo shown next to my pinky nail for size scale). No rhinestones are missing. The rubber covering of stitch inside the arm pits is flaking away due to age but the integrity of the stitch is perfect. The rhinestone hanger from the zipper seems to be missing, isn't noticeable. Could add something or wear as is. Fabric tag has been removed. Other similar knits in this era are nylon and wool blends, but I do not know the nature of the fabric. This is just a guess.
